Re: 3.0 140 mercruiser
hey there rod knock, the motor is a 2001 and the boat is a 1987, this is the little black ignition control module in the distributor with the 2 connectors on it that come out of the distributor, it looks just like the one on the gm vehicles, and even plugs in and runs the boat, but i dont know if it adjust the timming correctly or not (advance)or if merc has a different prog in there module for advance. thanks rod knock
